OspA (outer-surface protein A) is specific to Borrelia ONLY.  I have IgM antibodies to OspA and to no other bands.  What's going on here?

Serotype to other +?: OspA serotypes 3–6. Phase I/II studies with the multivalent vaccine have been initiated in humans to determine the optimal dose, formulation, and booster interval in Borrelia seronegative as well as Borrelia seropositive individuals. American patients with Lyme arthritis commonly had antibody responses to OspA, BicA, and OspD. I am not clear as to what may cross react with other substances +? ...Read more
